To establish the workflow between TeamForge and TestLink, you must first create requirement tracker artifacts and a defect tracker in TeamForge.
You can create as many requirement trackers and artifacts as you want for a TeamForge project. This includes artifacts such as epics, stories, tasks and so on. However, you must create only one defect tracker for a project, because for every single instance of a failed test case in TestLink, a corresponding defect artifact is created in TeamForge automatically under this single defect tracker.
